Explanation:
I.e.
x
=
3
−
2
y
(from first equation)
Now substitute
x
above into second equation:
−
2
(
3
−
2
y
)
+
y
=
1
−
6
+
4
y
+
y
=
1
−
6
+
5
y
=
1
5
y
=
7
Therefore
y
=
7
5
Now substitute the
y
-value into the equation to find
x
:
−
2
x
+
7
5
=
1
−
2
x
=
5
5
(
=
1
)
−
7
5
x
=
1
5
Thus,
x
and
y
for the 2nd equation
=
1
5
and
=
7
5
.
